Amphibians & Reptiles

To date these are the only photos we have of amphibians from Selsdon Wood and there are no sightings of reptiles.

---- Tadpole development - a series of photographs by Tony Flecchia ---- 

The frogspawn in the Jubilee pond (shown in the first photograph) never hatched in situ. By the time the little tadpoles were ready to emerge the spawn had collapsed and we assumed the stagnant water in the pond had killed it. Fortunately, we had removed a batch of spawn earlier to rear at home and the photos of the developing tadpoles below were taken from this. However, the high attrition rate was troubling and as deaths continued it appeared that the problem was virtually certain to be the ranavirus disease that has been killing frogs worldwide since about 1980. It also affects the developing tadpoles and the symptoms were all evident in these tadpoles, lethargy, loss of feeding, swollen abdomen and pigment changes. Apparently the water that infected frogs enter can become a home for the virus, reinfecting any later frogs and tadpoles, so there is not much hope for our still water pool. The disease also lethally infects all other amphibians and reptiles - which may explain why we have no other sightings. The froglet in the final photograph in the sequence was the only one remaining from the 80 tadpoles that we started with - and sadly it too died the following day

An up-to-date listing of all the Birds seen in Sesldon Wood is provided at the top of this page. 

The list will be updated when new species are seen additions could occur at any time, particular during migration.

Over the years we have installed many bird-boxes throughout the wood including, in 2012, 5 tit boxes and 2 owl boxes.

---- Bats ----

Bats present particular challenges when it comes to researching and monitoring their presence in a given area. For many years it was believed that Selsdon Wood (SW) was home to Common Pipistrelles and nothing more. It was our attendance on bat walks at Wandle Park with Meike Weiser, Community Conservation Partnership Officer at Croydon Council, that piqued our interest in acquiring an Echo Meter Touch 2 bat detector for IOS, after seeing one in action in the hands of one of the attendees. It was a revelation - full spectrum detection and auto ID, it made the bat world immediately accessible.

With the hobbyist version in hand, we joined the FSW bat walk in July 2018. A visit to Leafy Grove revealed Common Pipistrelles and the group later moved into Great Field to walk back to the car park field. We hung back some 100 yards and as we traced the edge of Steven’s Larch the Echo Meter lit up and confirmed that the large bat that flew slowly over our heads  and the group ahead was a Serotine.

This was the catalyst that indicated there may be more to discover in SW and during the subsequent months (until hibernation) we established (mainly in the corner of the car park, to the right of Greenhill Way as you look up the hill), that there were, at that point, four species present, either resident or visitors to the wood:

Common Pipistrelle, Serotine, Noctule, Leisler

In September, we had a recording the Echo Meter identified as a Bechstein’s bat, one of the UK’s rarest, with a population of only 1,500 residing mainly in the South. The recording was examined by Philip Briggs from the London Bat Group who advised that it could be either a Bechstein’s or a Natterer and in the final analysis felt it should be logged as the latter, so we ended 2018 with five listed species for SW plus recordings indicating the likely but at that point unconfirmed presence of Whiskered bats.    

In 2019 the hobbyist version of the Echo Meter gave way to the ‘Pro’ version with a more sensitive microphone and extended tuning options. With this enhanced equipment the current year has seen recordings that increase the species list to nine. 

Common Pipistrelle, Soprano Pipistrelle, Nathusius Pipistrelle (a guaranteed detection that has been independently verified by both Philip Briggs and John Russ, who are noted experts), Serotine, Noctule, Leisler, Natterer, Whiskered,   Brown Long Eared.

The most exciting thing about the current position is we’ve edged closer to there being Bechstein’s present as a new recording on April 20 was garnered and forwarded to Philip Briggs for analysis. He responded: “It’s probably either Bechstein’s or Natterer’s bat but it’s trickier to be more precise than this as the call parameters are generally within the range for both species, with the end frequencies occasionally going a bit lower than Jon Russ’s book gives for Bechstein’s bat or a bit high for Natterer’s bat. I notice the calls are very clipped which could potentially reduce the reliability of measurements. Sorry I can’t be more conclusive, but it’s likely to be one or the other!”

Bats are a key indicator of the health of ecosystems. In order for bats to prosper, there needs to be plants and trees that support the requisite insect populations and so forth. That SW has nine species present, either resident or as visitors, is very welcome and we look forward to broadening and deepening the knowledge of these amazing and unique animals in the wood.

The map below shows the locations at which bats of each species have been observed (as of 16/7/19). 

The colour code is:

RED - Common Pipistrelle 
GREEN - Soprano Pipistrelle
LIGHT BLUE - Myotis (ie Natterer and/or Bechstein's, as well as Whiskered and/or Brandt's)
DARK BLUE - Noctule
PINK - Leisler
BROWN - Brown Long Eared
YELLOW - Serotine

In February 20121 using the the BTO Acoustic Pipeline (see above) we had confirmation of 7 species new to SW records. These findings are tentative as the accuracy level of the classifier is unknown and as these were identified from ultrasound recordings there are no photographs. However, it will be interesting if we have any confirmation in future years.
